How do I iterate over a set in Python?

You can iterate over a set in Python using a for loop. Here's an example:

my_set = {1, 2, 3}
for item in my_set:
    print(item)

What if I want to perform an operation on each item?

You can easily perform operations within the loop. For example:

my_set = {1, 2, 3}
for item in my_set:
    print(item * 2)

This will print each item multiplied by 2.

Can I use list comprehension with sets?

Yes, you can use set comprehension! Here's an example:

my_set = {1, 2, 3}
new_set = {item * 2 for item in my_set}
print(new_set)

This creates a new set with each item multiplied by 2.

Are there any methods specific to sets I should know about?

Yes! Sets have methods like add(), remove(), and union(). For example:

my_set.add(4)
print(my_set)

This adds 4 to the set.
